Answer 1

I get exactly the reported error if ccache is enabled, when using CMake's Xcode generator. Disabling ccache fixed the problem for me. Below I present a fix/check that works for MacOS, but should work similarly on other platforms.

Apparently, it is possible to use CMake's Xcode generator (and others) also in combination with ccache, as is described here. But I never tried it out myself.

# 1) To check if ccache is enabled:
echo $CC
echo $CXX
# This prints something like the following: 
#     ccache clang -Qunused-arguments -fcolor-diagnostics. 
# CC or CXX are typically set in the `.bashrc` or `.zshrc` file.

# 2) To disable ccache, use the following:
CC=clang
CXX=clang++

# 3) Then regenerate the cmake project
cmake -G Xcode
